Absorption of heat into a superconductor-normal metal-superconductor junction from a fluctuating environment
Juha Voutilainen, Pauli Virtanen, Tero T. Heikkilä
We study a diffusive superconductor-normal metal-superconductor junction in an environment with intrinsic incoherent fluctuations which couple to the junction through an electromag…
Energy relaxation in graphene and its measurement with supercurrent
Juha Voutilainen, Aurelien Fay, Pasi Häkkinen +3
We study inelastic energy relaxation in graphene for low energies to find out how electrons scatter with acoustic phonons and other electrons. By coupling the graphene to supercond…
Physics of Proximity Josephson Sensor
Juha Voutilainen, Matti A. Laakso, Tero T. Heikkilä
We study the proximity Josephson sensor (PJS) in both bolometric and calorimetric operation and optimize it for different temperature ranges between 25 mK and a few Kelvin. We inve…
Nonequilibrium phenomena in multiple normal-superconducting tunnel heterostructures
J. Voutilainen, T. T. Heikkila, N. B. Kopnin
Using the nonequilibrium theory of superconductivity with the tunnel Hamiltonian, we consider a mesoscopic NISINISIN heterostructure, i.e., a structure consisting of five intermitt…
